Forklift dc contactor are mainly used to control switching on/off of power supply of storage battery car,electric forklift, electric winch, electric car,excavator, air conditioner in vehicle.
Application
Forklift dc contactor are mainly used to control switching on/off of power supply of storage battery car,electric forklift, electric winch, electric car,excavator, air conditioner in vehicle.
The forklift DC contactor is compact in design, easy to install, and equipped with reliable overload protection and short-circuit protection functions, Forklift dc contactor ensure that the current is cut off in time in an emergency to prevent accidents.
